Taking into account that, it is possible to extend these functionalities by the different types of boards, kits , accessories and applications compatible with Arduino .

For its part, Raspberry Pi consists of a simple board computer that exhibits great power to simplify learning for users and allow them to carry out basic tasks. Taking into account that, its main objective is based on teaching computer science in a versatile way . It also offers the ability to compile programs to run on it .

Now, both Arduino and Raspberry Pi are classified as very peculiar boards in the world of programming that support software development in order to implement great ideas without the need for advanced knowledge . For this reason, in this post, we want to emphasize the best projects to program with Arduino and Raspberry that exist so far .

Learn about the best projects to program with Arduino on your own

Fortunately, Arduino boards have all the essentials to be able to connect peripherals to the inputs and outputs of a microcontroller . In this sense, it has the necessary components to be able to link with a computer through serial communication . Added to this, thanks to the fact that it supports different accessories and compatible applications, Arduino is characterized by its versatility in providing various uses .

Among them, the most relevant of all are the following : Creation of integrated environments, programming apps, projects based on the Internet of Things, software development and 3D printing applications . So, fans of the world and DIY maker culture, have decided to take advantage of the remarkable advantages of Arduino to implement actions that are of great interest in the world of electronics, mechanics, robotics, automation, etc .

Therefore, today, different attractive projects are distinguished that can be programmed with the help of Arduino and here, we mention the best 15 of them:

Radar to detect objects

It qualifies as one of the most suggestive Arduino projects, so far. Which, basically, refers to a radar that has the ability to detect the presence of objects by means of an ultrasound sensor that has a coverage or 180-degree turn and a range of up to 4 meters . This sensor is based on an HC-SR04 and can be obtained for a low price.

In addition to this, the project requires an Arduino board, the IDE associated with Arduino , a servo motor, a breadboard, and jump cables . Once you have the required materials on hand, you must use a cardboard support to proceed to connect the ultrasonic sensor to the servomotor that will be linked with a screw. Furthermore, said servomotor has to be secured to the plate using an elastic band .

A smart traffic light

As far as Arduino projects are concerned, one of the most representative is the smart traffic light . This being the case, a traffic light that, unlike the other common ones, offers the possibility of controlling two traffic lights at the same time, depending on whether there is a car waiting to pass or not. In this way, the objective of the project is based on simulating a crossing with traffic lights that detect the presence of cars in order to activate or deactivate them in a timely manner .

Therefore, in an initial state, a green traffic light can be observed. Thus, as long as there are no cars at the other traffic light, it will also remain green . But, once a new car arrives at the red light, the latter will turn green and close the other light after a few seconds have elapsed. In such a way, they will alternate with each other always .

Now, when building this project with Arduino, users will have to use an Arduino board with an ATMega328P microcontroller . Additionally, it is necessary to have 6 200 Ohm resistors, 2 10 K Ohm resistors, a total of 6 LEDs (or even more), as well as 2 push buttons and a lot of imagination on the part of the amateur maker .

Robotic arm

In this case, the Arduino is openly linked to the world of robotics . Well, it is an arm specially designed to take any object with the help of tweezers and, at the same time, it manages to avoid collisions with obstacles. In this way, it is based on a robotic arm project that has the ability to move any small element from point A to point B, detecting any obstacle between both positions.

In this sense, in case of encountering an obstacle during the journey, the robot will make sure to find an alternative path so as not to collide and when it stops detecting the crossed object, it will fix itself in the indicated position to be able to resume the movement to a point B .

For this, basically, programming is implemented using the concept of Finite State Machine (FSM) and with them, it uses the advantage of showing speed. Well, with these, the main cycle will conclude in a matter of milliseconds. Apart from that, each FSM will be able to evaluate the current inputs to provide the correct outputs so that the program appears asynchronous and can perform several tasks simultaneously.

Added to that, in terms of hardware, the following materials or components are required to create the robotic arm:

  • An Arduino Nano R3 board .
  • A 6 DOF type robotic arm .
  • An HR-SR04 ultrasonic sensor (will be located on the right side of the arm end).
  • 6 MG995 or MG998 servos .
  • A 1 K Ohm resistor .
  • A DC 15A power supply.

The automatic opening bin

This is another of the most interesting projects that can be programmed through Arduino. Which is an automatic garbage robot that, without the need to receive a command directly, manages to open its lid when it detects garbage nearby and once it is inserted into it, the bin will close after a few seconds. That is to say, it has the ability to see when someone approaches their hand to throw garbage and thus, it opens automatically .

For its part, in terms of software, it only requires making use of the Arduino IDE . While, its hardware components are the following : An Arduino UNO board, a servo motor (Tower Pro MG996R), the servo arms, an HC-SR04 ultrasound sensor (can be generic), a UTSOURCE kit of electronic parts, a garbage container (whatever you want) and a piece of cardboard.

Among other details, it is worth noting that the code to compile this project from Arduino, focuses on a range of 50 cm so that the bin can be opened once it detects any element in that distance. Also, the servo has to be at 50 degrees to hit the top lid of the container in order for it to open and when three seconds of time is up, it will make a 160 degree turn so that the lid itself closes .

Voice controlled blinds

They refer to blinds controlled by Bluetooth that have voice attention functions . This means that they work as a voice-controlled system via Bluetooth and thus, it is possible to both open and close them on demand. In this way, it is possible to automate this element of the home that is extremely practical.

Luckily, it is a very inexpensive Arduino project where only the following components are required to carry it out : an Arduino Nano board, a motor controller, a HC-06 Bluetooth module, two 220 Ohm resistors, two push buttons, two gear motors and an LED. Apart from that, it is also necessary to have cables, soldering iron and welder, box cutter, hot glue gun and said glue, as well as cardboard.

Electric socket

It is one of the projects to program with Arduino that is more fun, among so many alternatives. Since, in this case, the creators are committed to providing optimal solutions dedicated to the playful world, since it is based on the simulation of a 6-sided dice that allows you to get a random number, automatically, with just pressing a button . Thus, a digit that will be represented by a screen or 7-segment display .

Therefore, to build this project, it is necessary to have on hand a 7-segment display, a pulsed display, a 220 Ohm resistor and a 10k resistor (pull down) and an Arduino Uno board . Now, when programming with Arduino, it is important to be very careful with random numbers because, if it is not done correctly, it is likely that you will always get the same sequence or the same number .

A selector of objects by color

This is a kind of machine that has the ability to organize the amount of items you need, specifically according to their color. Thus, this Arduino-based project consists of creating a color classifier with the help of an Arduino Nano board, a pair of servo motors, a color sensor, several jump cables, a socket, and the relevant programming from the Arduino IDE.

With this, initially, the machine will be able to hold the colored objects that you want to segment on its platform attached to the upper servomotor. Next, the servomotor starts to rotate and is responsible for transporting the bolus to the color sensor so that this component can detect the tone . Subsequently, the lower servomotor rotates to the particular position, while the upper one rotates back until the bolus falls on the corresponding rail .

Light tracker

This is characterized by being one of the most appropriate projects for the newest. Since, it requires little time for its development and, in addition, the components that it needs are simple . Well, apart from the Arduino board to use, you only have to acquire a servomotor, two 470 Ohm resistors, two photo resistors and some cables to build the circuit.

From these, to create the light tracker, people will have to start by placing the two photo resistors on one of the servomotors that will be divided by the plate that segments the fields of vision. In addition to this, the resistors will be responsible for measuring the incident light at regular intervals, rotating horizontally thanks to the servomotor used.

Additionally, the Arduino IDE must also be used to be able to enter the source code of the system. Said source code will be the one in charge of determining that the servo rotates as long as there is a greater incidence of light in one of the resistors, so that the sensors register the same light. In this way, the Arduino- based structure will be able to follow the light trail of a flashlight and display it as if it were a magic trick .

Automatic spray gun

It is a very attractive Arduino project for fans of the maker world, since they will have the challenge of converting a spray gun into an automatic model that has a motion sensor . Through this, beyond its practical uses, people will achieve greater learning when it comes to Arduino. Taking into account that, as a result, they will get a pistol to cool off just by moving their hand or asking in front of it.

For its part, basically, to create said spray gun with motion detection you will have to make use of an Arduino board (either Nano, Uno, Mega, etc.), a PIR motion sensor, as well as an automatic trigger of raid, an NPN transistor, a diode, wire, and some wire cutters. In addition to this, you will have to rely on the Arduino IDE to load and add the specific code . Which, you can download it for free on some websites.

The connected scale

Controlling your current weight has never been so easy and attractive as it is with the connected scale designed by Arduino . Which has access to the IFTTT service to connect with other quantification accounts and has the ability to detect up to a total of 200 kg of body weight . In addition, unlike common scales, it is capable of connecting to the WiFi network and displaying the results obtained by means of an LED matrix .

For its part, it takes care of taking several measurements and in the event that the measured weight exceeds a specific value, it will be able to read the weight a certain number of times in order to compute the average weight of the person . On the other hand, when the user exits it, it will automatically restart in order to recalculate the weight of another person .

Now, to carry out this smart scale project, it is essential to have some critical components on hand . Among them, we point out the following: an Arduino board, an Espressif ESP8266 ESP-01, a DFRobot ESP8266 Firebeetle, an HX-711, a DFRobot 24×8 LED matrix Firebeetle cover and 4 load cells of 50 kg. Like, a 3D printer, Arduino IDE, Autodesk Fusion 360, IFTTT Maker Service, Adafruit.io, Fitbit, and Apple iOS Health.

Advanced planter

With the help of Arduino and at a low cost, you have the possibility of building an optimal autonomous garden system from which it is possible to control the humidity, temperature and the amount of light that the plants receive, automatically. Added to this, it exhibits the ability to water your plants when they need it and makes sure you get the light you require, with some artificial lights similar to natural sunlight.

To achieve this in a relevant way, it is necessary to make use of several sensors, among which the humidity sensor, the light sensor and the temperature sensor stand out. In addition, it has a couple of galvanized nails for humidity, uses a thermistor for temperature and uses an inexpensive photocell for light. Thus, with this system, users will not have to worry about complying with the regular schedule to expose the plants to the sun and water them.

Now, in the form of a brief notion, we emphasize what you have to do when building this project: You must plant the garden as it is done in a conventional way to make use of the Arduino board and connect the humidity sensors to it, to so load the code from Arduino IDE. Next, also connect the temperature and light sensor to splice the indicated relays on the power cables and attach an LED to the board . Finally, it only remains to configure the irrigation system.

MIDI controller

It is based on an ideal project for music lovers. Well, by means of the materials it uses and how it is encoded, it allows you to create an optimal DIY MIDI controller that has 4 knobs and 16 buttons . In addition to this, it works with an Arduino board where the appropriate program is installed, as well as with analog synthesizers and a 3D printer must be used to print its plastic case.

Among other details, this MIDI controller made by Arduino, works with any MIDI software and hardware, without limitation. Also, with the help of the Adafruit learning system, users will be able to create better . Taking into account that, this has sensors, buttons, LEDs and pads with alligator clips that facilitate the construction of the mentioned MIDI controller.

Car parking sensor

Without a doubt, this Arduino project is one of the most traditional. In that sense, its main function is to warn the proximity or distance that your car has from another vehicle or object when parking (or parking) and in this way, it av
